Analysis of The Susceptibility Value Dry Ink (Toner) From Raw Material Iron Sand Pasie Nan Tigo Beach and Rice Husk Biomass

Abstract

The competition engaged in manufacture of the dry ink industry (toner) is increasing, with many types of dry ink (toner) emerging from various brands. This makes each brand compete to try to create quality dry ink. However, this is not easy, because raw material for making dry ink is expensive and stickiness of dry ink on the paper can change if the material is modified. The dry ink in this study was made by modifying the raw materials using natural mineral magnetic (Fe3O4) from the iron sand of Pasie Nan Tigo beach, activated carbon from rice husks biomass, and organic polymer Acacia Senegal. Taking into account the mixture of three raw materials in made of dry ink (toner) will affect the characteristics of dry ink (toner), one of the characteristics affected is the large content of magnetic minerals (Fe3O4) in it, it is necessary to test the value of susceptibility in dry ink (toner) to see the amount of magnetic minerals that are still present in the dry ink after mixing. The tool used for testing magnetic susceptibility values here is Bartington Magnetic Susceptibility MS2B. The purpose of this study is to produce quality dry ink with good dry ink paste power (toner) with based the characteristics of the susceptibility value of the dryink (toner). This research method uses extraction and coprecipitation methods and emulsion polymerization methods to increase the strength of the stickiness dry ink (toner) on paper. The results of characterization obtained by range 11924.60 x 10−8m3/kg until 27916.97 x 10−8m3/kg.
